Where did you get these from? I'm asking because I sent this patch last
year (or at least I wrote it and we discussed it on IRC, since I can't
find an email archive link to it), and back at the time the picture
aspect ratio was the big question mark. My recollection is that
CEA-861-F introduces these new picture aspect ratios in the mode tables
but never specifies their values. As a matter of fact, the AVI infoframe
where these values are used only has space for 4 values (none, 4:3, 16:9
and reserved).
Would you mind pointing me at the specification for these values?
Thanks,
Thierry
